Let's do a search. And let's pick the one that's closest to me. We'll put a check mark next to that. And click on "next". And now I select my date. I recommend that you try to schedule your exam at least a month out. And the reason I say that is sometimes testing centers are very busy. It's difficult to get in tomorrow or this week or next week sometimes. Things tend to book up. So, let's go a ways out. Let's say I want to register for October 15. I can select a time. I'll say 9 AM. Once I select a time, I click on "select appointment". It says my appointment is selected.
What can you tell me about the use of out in these two examples?
